Software and driver considerations

The USB-KW019032 includes OpenSDAv2.1 (CMSIS-DAP), a serial and debug adapter circuit that

includes an open-source bootloader, and debug interface software. It bridges serial and debug

communications between a USB host and an embedded target processor. The hardware circuit is based on

the Kinetis K22F family. You can find more information in the KW019032 Quick Start Card.

To enter the bootloader mode and re-flash the CMSIS-DAP application, hold down the SW2 button while

plugging the USB-KW019032 board to the PC.
